Pass by reference via 'return' a variable...

Hi all,

Quick question: If I have a function which populates a large array (ie.
reading rowsets), is it better to pass in a reference to a variable to
accept the data, or should I just create, populate and return the array
from the function?

Thanks in advance!

Passing reference is preferred because passing an array back is seen as
more of a 'hack'

I guess the question is: will PHP optimize this for me so that the
entire contents aren't copied out of the function, or do I have to pass
in a reference?

You have to pass a reference.

Folks, I've asked this before but never got any response but its important and I thought I'd pitch it again (hopefully a bit clearer)... One can pass data from one function to another either by passing a copy, or passing by reference. My understanding of passing by reference (putting the & before a variable during the function declaration) means that the original data is used.

Hi folks, I would be interested to hear peoples views on whether or not 'pass by reference' is allowed when using a Web Service method. The thing that troubles me about pass-by-reference into a WebService is that essentially we are passing an address of an object which resides on the 'local machine' i.e. a local machine object address. Surely when the WebService method is called and run 'on the server', the reference type will be...

I've read that C allows two ways to pass information between functions: o Pass by Value o Pass by Reference I was talking to some C programmers and they told me there is no such thing as pass by reference in C since you are just passing an address (or a pointer value address I guess?). So I was wondering is this correct?

Why does VB.NET V2 force me to pass by value for my set function? When I try to change it to const byref it gives me a syntax error. It seems very inefficient to be passing strings around by value when a reference to a constant string object will do fine (all we are going to do is copy it). In my case, would the byval for the set function cause a superfluous copy? Thanks, Siegfried class person dim m_name as string

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
